Engine started before disassembly, now no spark.

Asked by Feb 12, 2019 at 02:30 AM about the 2006 Mercury Mountaineer Premier AWD

Question type: Maintenance & Repair

I changed intake manifold gaskets and now it won't
start. It cranks but no start. I've tried to start with
starter fluid to no avail. Then I checked for spark
and realized I'm getting no spark from any of the
plugs. The truck started fine before I changed the
gaskets. I'm not too sure what could have
happened and I've already checked over everything
several times.

Look for a disconnected lead to your distributor or coil (either ground or power). Also, make sure you put the rotor back into the distributor (if so equipped).

Well I'll start by saying I've checked over the entire thing for disconnected wires or even anything maybe loose to no avail. I don't think it has a distributor, and it has a coil on plug system. Separate coils for each plug. I'm going to go out there right now and see if I can find any ground that's loose or disconnected. But I'm leaning away from something being disconnected. Anywhere specific I should be looking?

Now I've changed the Crank Position Sensor and it still won't start. Running out of ideas here.
